Hanna Instruments Buffer Solution Bottle, 500ml

These Hanna buffer solutions are prepared and ready to use in accordance with the National Institute of Standards and Technology (NIST). All solutions show a batch number, an expiry date, and the correlation table between pH and temperature. All bottled solutions are sealed with an air-tight, tamper-proof seal to prevent any Carbon Dioxide from entering and causing a change in the pH buffer value.

The pH 4.01 buffer is extremely stable and represents the mid-way point in the acid range of the pH scale. The pH 7.01 buffer is ideal for those requiring a neutral reading, and the pH 10.01 buffer is suitable for those needing an alkaline reading.

Buffer solutions should be stored at 25 °C, away from direct sunlight, for accurate readings. Three buffers to choose from: pH 4.01, pH 7.01, or pH 10.01. Each is in a 500ml bottle and has a 24-month shelf life.
